Description

Technical Field

[0001] The utility model relates to the technical field of mine support equipment, in particular to a broken roof support device for an underground mine. Background Art

[0002] Broken roof in underground mines refers to the phenomenon of broken and collapsed roof during underground mining. This kind of broken roof will pose a serious threat to the safety of the mine working face and may cause accidents and production interruptions. Therefore, underground mines need to adopt appropriate support devices to protect the safety of miners and the stable operation of mines.

[0003] As mining progresses, the underground rock strata will be subjected to tremendous ground pressure and self-weight pressure, which will gradually be transmitted to the roof. The roof is an important protective layer for mine pipelines and equipment, and is subject to tremendous ground pressure and rock strata changes. However, due to factors such as geological conditions, ore layer structure or mining methods, the roof of the mine often breaks and collapses, which poses a serious threat to the life safety of workers and the normal operation of mining equipment.

[0004] In order to ensure the safety of miners and the normal operation of mines, underground mines need to adopt effective roof support devices. In order to bear and disperse the roof load, enhance the stability of the strata, prevent the roof from breaking and collapsing, and ensure the safety of underground mining operations, however, when using existing devices, a large number of brackets are often required to support the support plates, occupying a large area in the underground mine, affecting traffic, and unable to adjust the width of the horizontal support as needed to adapt to a wider range. Therefore, based on the above problems, an underground mine broken roof support device is proposed. Utility Model Content
